TO ALL WHOM IT MAY CONGERN:

Be it known that I, C. I-I. KNOX, of Mount Pleasant, in the county of Henry, and Staterof Iowa, have made an improvement in Wringers; anclI do hereby declare that the following isa full and exact descriptionv ot" the same, reference beingV had to the accompanying,rv drawings, and letters of reference marked thereon, making a part of this description, in which-',

Figure l is an elevation of my invention as attached to the end of a washing machine.,A

Figure 2, an elevation of the end of wringer, showing the lever which holds the rollers together, and a part of the connecting-rod.

Figure 3, a perspective representation of the lower cog-wheel.

Figure 4, a plan view of the suspended roller and the level` to which the weight'for regulating the pressure of the rollers is applied. i v

YFigure 5, an elevation of the double cogwheel which is used in conjunction with wheel shown at fig. 3 in turning the common rubber rollers of a wriuger.

The nature of my invention consists, first, in the use of pivoted levers made to bear upon the ends of the upper roller of the common wringer by means of connectingq'ods attached to said levers, and a suspended roller at or near the bottom of the n'ashingbox, and a weighted lever attached tothe end of the bottom of said box, bearing upon said roller, by which-means both ends of the upper roller will be held against the lower roller with equal force, whetherthe articles to be wrung are put in the wringer at. the centre or near either end, which is not the case when metallic or rubber springs are used at each end of the wringer. Second, inthe use of an upper double cog-wheel and a central lower pinion, the former having co'gs occupying alternate spaces, and the latter being arranged to mesh in said double cog-wheel, and move the rollers of' the wringer, notwithstanding said rollers be forced a greater or less distance apart, as when wringing thick or thin articles. This latter arrangement is very important, for the common single cog-wheel is found to be nsuliicient to turn the rollers of the wringer, especially when they are `closed together or far apart, because in the former case the cogs of said wheel are apt to bind, and in the latter case they are apt to be thrown out of gear, or fail to mesh, and only work well when mediumsized goods are put between the rollers,

I claim that the use of my double cog-wheel will obviate the above-named dilliculty, as it works equally well whether the rollers of the wringer are far apart or close together; and as the cost of making my style of gearing is but little more than that commonly used, and the diherence in friction merely nominal, the advantage gained in this valuable household article is great, not only in its durability but inthe convenience of operation. I know that double cog-wheels have been used before, but not for this purpose; I therefore consider the inven tion a matter of combination.

In order to enable others to make and use my invention, I have marked corresponding parts with similar' letters, and will now give 4a detailed description.

A, iig. 1, represents the end of a common washing machine, to which my wringer is attached. B C show the frame, and D the rollers of a common wringer, the ends B being attached to box A in the usual manner. E, g. 2, represents a metallic plate, two of which are used, one at each end of the wringer, and rigidly attached to the parts B by al screw, g, or otherwise. These plates E are pivoted at L to levers I, which have circular bearings J, figs. 1 and 2, made to lit tbe ends of the upper roller D, and hold it i'n position against lower roller D. Connecting-rods K` are secured to levers I, and extend downward to av point a little below the bottom of box A, and are attached to a roller, L, lgs. 1 and 4. A lever, M, is hinged to boxA at N, and is made to bear upon roller L and force it downward, by which means the levers I are made to press upon the ends of upper 4roller D, and hold it with suitable force against lower roller D. It will be seen that lever M projects longi* tudinally under the machine A, and has common notches O in its top, by which means said lever is not in the way, and canhave a suitable weight hung in either of said notches to regulate the pressure of said levers I upon roller D, as may be desired, for thepurpose of wringing. B represent the upper double cog-wheeh'and S the double pinion used to operate rollers-D. It will be seen at iigs. 1 and 5 that the cogs of the upper wheel are made to occupy alternate spaces, and `that pinion S, `fig. 3, is arranged to mesh into said cogs, and thus cause rollers D D to have the same motion. I am not particular as to the material used, but prefer 'galvanized iron,

it 'being cheap "rand not liable to rust. 4'lli'e feller L una the lever M, however, may be made of wood, and answer a. goed pupose. l I

Having thus described my invention, what I'des-ire to secure by Letters Paftent, is- 1. The rrangement und combination of lever M, hinged to box A, roller L, rods K, levers I, and 'plate 0,.

.'farmnged toopemte uppez` roller D, as set forth.

2. The double cog-wheel P P, arranged to opera-te in combination with double pinion lS, for turning bhe rollers D D, substantiallv as described.
